This work is concerned with the synthesis of neutral dioxovana- dium(V) and dioxomolybdenum(VI) complexes with tridentate ONN pyri- doxal S-methylisothiosemicarbazone (PLITSC) of the respective formulas (VO2(PLITSC-H))·2H2O and (MoO2(PLITSC-2H)). Structural X-ray analysis of the vanadium complex showed that it has an almost ideal square-pyramidal structure, while the molybdenum complex is supposed to have a polymeric oc- tahedral structure. In addition to elemental analysis, both complexes were cha- racterized by conductometric and magnetometric measurements, as well as by IR, UV-Vis, 1 H- and 13 C-NMR spectra.
